Question

The aim of this lab is to familiarize yourself with reading and processing directories as
well as extracting file attributes using the stat() system call. You are essentially writing
your own version of the long format of the ls command. You will need to customize your
output to match the following specifications:

-o: specifies the minimum age of the files (modification timestamp) to be listed fromthe target directory. The -o argument will be followed by an integer (as a separate parameter to make things easier if you wish). This integer will represent the minimumnumber of days old the files can be in order for them to be included in your listing.
As an example "-o 3" passed as arguments would mean: list all files that have been
modified more than 3 days ago (from the current system time).
